Longfellow

Half-way up the hill, I see thee at last, lying beneath me with thy sounds and sights -- A city in the twilight, dim and vast, with smoking roofs, soft bells, and gleaming lights.

Two Bodies in One

Two bodies have I
Though both joined in one.
The more still I stand,
The quicker I run...

Tick-Tack-Toe Game

Tick-Tack-Toe
David and Angela play a game of tick-tack-toe. In this game, the players try to get three circles or three crosses in a row (horizontal, vertical, or diagonal).

They follow the following rules:

A player always tries to win: if a player can place his own symbol (X or O) in a row which already contains two of his own symbols, he will do so.

A player always tries to avoid that his opponent wins: if a player can place his own symbol (X or O) in a row which already contains two of the symbols of his opponent, he will do so.

Of course, the first rule has precedence over the second rule, because the game can be won in this way.

In the game shown on the right, 6 moves have been done. David plays with crosses (X) and Angela plays with circles (0). However, we don't know who started the game.

Who will win this game?



If you're like me, you may be having trouble seeing the image of the board I tried to create. So here's a more basic image:
O | O |

O | X |

Moon Cable

A large space agency has decided to build a base on the moon. For this purpose, a cable must be laid around the moon's equator. When the cable is laid, it turns out to be 1 meter short. In a quickly arranged meeting, it is decided to investigate the possibility to lay the whole cable in a groove.

How deep does the groove need to be to make this work?

The agency's director considers digging a groove, no matter how deep, around the entire circumference is too expensive. He suggests to lay the whole cable just a bit north of the equator. How many meters north of the moon's equator should the cable be laid to settle the problem of the lacking 1 meter of cable?

Help Win an iPad2

Hi all,
I never do this, but I'd like to make a personal appeal.  My daughter was entered into a contest to win an iPad2.  She painted a pottery piece at PYOP for her teacher at school.  The lady who runs it liked it enough to enter it into her summer contest to win an iPad2.  At six years old, that would be quite a prize.

If you have a facebook account, please head on over to the PYOP album (https://www.facebook.com/media/set/?set=a.10150194490771739.307688.40310146738) and like here photo (the one with the butterfly).  In case you're wondering, it's a dunk mug.  You can put cookies down at the bottom, for dunking!

Thanks for helping out!  We'll be back to our puzzles on Monday.  Happy father's day to all the dads out there!

Ants on a Board


There are 100 ants on a board that is 1 meter long, each facing either left or right and walking at a pace of 1 meter per minute.

The board is so narrow that the ants cannot pass each other; when two ants walk into each other, they each instantly turn around and continue walking in the opposite direction. When an ant reaches the end of the board, it falls off the edge.

From the moment the ants start walking, what is the longest amount of time that could pass before all the ants have fallen off the plank? You can assume that each ant has infinitely small length.

Generous Buzz


When Buzz gathered his 2001 records for his CPA, he found that he had made six donations, each for a different amount of money and totaling $1500, to six local youth sports teams, including a softball team. Given the data below, can you find how much in sports deductions Buzz has for 2001: the contribution to each team and the sport the team plays?

  1. Buzz donated twice as much to the basketball team as he did to the Knights.
  2. The contribution to the Comets was less than that to the football team.
  3. For his donation to the soccer team, which was $50 more than he gave the Rovers, the soccer team advertised Buzz's gas station on the back of their jerseys.
  4. The Lions got $150 more from the service station operator than the baseball team did.
  5. The smallest donation of the six was for $50.
  6. The Hawks received twice as much money from Buzz as the soccer team.
  7. Before actually seeing the receipts again, Buzz thought that his largest donation had been $600 and that he had given the hockey team $250; he found that the largest contribution was for less than $600 and that the hockey donation was for less than $250.
  8. Buzz gave the Knights $50 more than he gave the Devils.
  9. The largest donation wasn't the one to the youth basketball team.

Six of One

The expression, "Six of one, half a dozen of another," is commonly used to indicate that two alternatives are essentially equivalent, because six and a half dozen are equal quantities. But are "six dozen dozen dozen" and "a half dozen dozen dozen" equal?

Teacher is so Smart

After studying roman numerals for a short time, the teacher had given the class some free time.  Sally's teacher walked up to her desk and saw that she had written:
XI + I = X
on her paper.

He was quick to point out her mistake.  Sally protested, saying she had it right.  After demonstrating what she meant, the teacher apologized and moved on.

What did Sally point out?

Random Walk

A drunk leaves a bar (rather forcefully).  After standing up and dusting himself off (rather unsuccessfully), he decides to walk home.  Unfortunately for him, he has no idea where home is and has no way of deciding which way to go.  He is on a street traveling east-west only, making things simpler for him.

With each step, he's just as likely to turn around and walk back in the direction he came from.  After 20 steps, how likely is it he will be back where he started from (right in front of the bar)?

Split the Tab

You've been out to a restaurant with a group of people from work. The bill is now on it's way. Time for either a bit of philosophy/game theory. What's the best way to handle the bill? You have three choices: Split the bill evenly, pay for what you ordered, or got to the trouble of asking for separate checks?

For a good write up on the problem, try mindyourdecisions.

What is the largest number of bitterballs that cannot be ordered in these portions?
